Fast-import/fast-export plugin for Bazaar

Bazaar Fast Import is a plugin providing fast loading of revision control
data into Bazaar.

It is designed to be used in combination with front-end programs that
generate a command/data stream for it to process. Front-ends are available
for a wide range of foreign VCS tools including Subversion, CVS, Git,
Mercurial, Darcs and Perforce. New front-ends are easy to develop in whatever
programming language you prefer, making Bazaar Fast Import useful for teams
needing a custom migration solution.
